Answer:
Answer:18+4.5
Step-by-step explanation:
This shape is a triangle with a semicircle connected to it
and this triangle is a right triangle so side A=B
that means the other leg is 6.Knowing that we can solve
The formula for the area of a triangle is (base×height)÷2
so that means 6×6 equals 36 and if you divide that by 2 you get the 18.
Now we will deal with the semicircle. We know that both of the legs are 6 so that means the diameter is 6 and now we solve 6 divided by 2 equals 3 and we will have to square that and we will 9 and since it is a semicircle we have to divide it by 2 and that will give us 4.5 and since we have to express it in terms of pi it will be 4.5(pi) and then we add both of the areas
giving us 18+4.5(pi)
and do you go to RSM
The total snowfall for listed 10 days is 349 cm.
Further explanation:
The sum of snow fell each day will give us the total snowfall for 10 days.
Given:
Snow fell on 10 days:
14 cm, 13 cm, 7 cm, 3 cm, 11 cm, 14 cm,
28 cm, 108 cm, 84 cm, 67 cm
